PixelSky AI pixel light board

PixelSky is a pixel LED board paired with a browser-based editor. Users draw or generate animations with AI from text or images, preview them live, and push them to the board, which can also show the time and weather. The team built the whole stack: custom LED matrix PCB, ESP32 runtime, web editor and enclosure.
